Board game company Wizards of the Coast has filed a lawsuit against Cryptozoic Entertainment and Hex Entertainment, claiming that digital card game Hex: Shards of Fate is a clone of WotC's Magic: The Gathering.

However, WotC this week has alleged that Hex: Shards of Fate infringes on its own properties, including multiple entries in the Magic series, such as the Duels of the Planeswalkers video games.

"Hasbro and Wizards of the Coast vigorously protect our intellectual property," reads a statement from the company. "This infringement suit against Cryptozoic demonstrates that while we appreciate a robust and thriving trading card game industry, we will not permit the misappropriation of our intellectual property."

The lawsuit includes claims of copyright, patent and trade dress infringement. WotC previously submitted an official complaint in March.
